Some of the carbon dioxide absorbed by plants during photosynthesis is radioactive.

植物在光合作用中吸收的一些二氧化碳具有放射性.

As a result, the activated carbon made with oil palm shells, impregnated with 2% TEDA-2% KI, is the best and can be used as adsorptive materials in filter for removing radioactive waste from nuclear power stations.

经筛选所得的以2%TEDA～2%KI浸渍的油棕炭，是其中对碘和甲基碘吸附性能兼优的炭种，可用作核电站中除碘过滤器的吸附材料。

When the organism dies, no new radioactive carbon is assimilated.

机体死后, 不能再吸取新的放射性碳.
